Source code loading from .txt file :P

[likemau5]

Hi, let's say i have source code for enemy saved in .txt file and need to load it to variable, and then run this code from that variable.

something like this:

function love.load()
monsterhp = 15
--want to load the .txt file contents here
end
function love.update(dt)
-- running txt contents here
end


Is it even possible?

Make a .lua file for your enemy! Name it enemy.lua and you can use a require-command to use it in your main.lua:

Code: Select all

require("enemy")

You can define functions and variables in enemy.lua and use them by adding "enemy." without quotes in front of them in the main.lua. No need for txt-files here. If you look at some source code from other games, you can see that this is common practice. I suggest checking out http://stabyourself.net for some examples. The games in the sidebar are made with LÖVE and have the sources available.

Sure. Look for loadfile() / loadstring() / dofile() Lua's functions.

Do this:

Code: Select all

-- load file contents as a string
contents = love.filesystem.read("/path/to/file")

-- execute string
loadstring(contents) ()

-- use this if you want to "catch" any errors that are thrown when running this string of code
-- assert(loadstring(contents)) ()

This might also be of interest to you if you are running foreign untrusted lua code.
